IMPROVED DEVICE FOR CUTTING UP COMROSlTlON ORNAMENIS USED FOR PICTURE AND MIRROR FRAMES, ARCHlTECTURAL PURPOSES, dc.

Specification forming part of Letters Patent No. 86,4 16, dated September 9, 1862.

the t'ollowinglis a full, clear,and exact descrip tion of thesame, reference being had to the accompanying drawings, making a bar"; of this,

specificatio'n, in which- 1 Figure 1 is a plan or top viewlof my iuven-' tion applied to its work; Fig. 2, a detached inverted plan of the same; Fig. 3, a side sectional View of the sameapplied to its work,

a m, Fig. 1, indicating the plane of section.

Similar letters of reference indicate corresponding parts in the several figures The-object of this invention is to obtain a machine or device by which the composition ornaments used for picture-frames, mirrorframes, and architectural purposes-may be cut up-that is to say, cut from the base or bed of composition on which they are formed in basso-rilievo by molds. The composition used for the purpose is a plastic substance similar or analogous to glaziers putty; and

. hitherto the raised ornamenthas been cut from the bed or base manually by mcans'of a k nife-- an operation which requires considerable care and expert workmen.

By means of the'within-described invention the work may be done perfectly by almost any one, no mechanical skill being required in order to remove the ornament from-the base.

The invention consists in the employment or use of'aknife-stock composed of two parallel side pieces connected by transverse bars and a screw-rod, the knife being fitted in the stock and all arranged in such a manner as to effect the desired end.

To enable those skilled in the art to-fully understand and construct my invention, I will proceed to describe it.

A represenls a stock, which is composed of two parallel side pieces, a a, connected by transverse rods b near their ends. The side pieces, a a, may be of wood and the rods b of metal.

13 is a rod which passes transversely through the side pieces, a a, near their centers and is provided at one end with a head, 0, and has a screw-thread out onits opposite end to receive. a thumb-nut, O, as shown in Figsrl and 2. In the lowcr'edges of the side pieces, a a, there are made recesses d d to receive the sides of a knife or planer, D, as shown in Fig. 2. This knife or planer D is constructed of a flat piece of steel beveled at one end and at its upper:

side to form a cutting-edge, 0. (See Fig. 3.) This knife or planer is retained or held in proper positionin the stock A by means of the screw-rod Band thumb-nut C, the cutter,when screwed up, causing the side pieces, a. a, of the stock to pressor bind firmly against the sides of the knife or planer D in the recesses d d.

These recesses d d are rather deeper than the thickness of the knife or planer, so asto. admit .of thecuttiug-edge of the latter being adj nsted either flush with the lower surfaces of the side pieces, a a, or a trifle above them. (See Fig. 3,

in which the cutting-edge of the knife or planer is shown adj ustcd flush withthelower surfaces of a a in blue tint, and a trifle abovethem in red outline.)

E represents the ornament, and F the bed or base on which the latter is raised or formed by the mold, the ornament or base being of which the stock works or is shovedalong by hand. v

From the above description it will be seen that when the cutting-edge of the knife or planer is adjusted flush with the lower surfaces of the side pieces, a a, of the stock the ornamcnt E will, by shoving the stock aloug on the bed or base F, be out therefrom by the knife or planer, the ornament as it is cut passing over the knife, or rather the knife passing un-' der the ornament. (See Figs. 1 and 3.)

In cutting off the ornament it is essential that the out be not below thesurface of the bed or base F, as inthat event the ornament will be out with aburr around its edges, 2. portion of the bed orbase being removed with the ornament and greatly deteriorating the latter so far as appearance is concerned. Hence in cutting 0d the ornament by hand considerable practice is necessary in order to avoid this contingency, which cannot occur in using my invention if the knife or planer be set correctly;

mid in order to effectually preventeny re sn-l t,

. Having thus described my illVClibjOi], what/I do claim ashew; and desire to secure by Letters Patent, is, i

The steel: formed of two side pieces, 2a, connected by rods b or their equivalents,- and provided with a serew-rod, B, and thumb-nut- C, in connection with the knife or planerD,

fitted ,in the 'etockA, substmi tiall y as shown and described, and all arranged to be used with orapplied to the bed 61' base of the ornament, for the purpnse'herein set; forth. v
